The ideal candidate will have strong hands-on experience with modern API frameworks, microservices architecture, and cloud-based solutions, as well as a track record of collaborating with cross-functional teams to deliver seamless integrations. Experience with Databricks is a plus, particularly in integrating APIs with big data pipelines and analytics solutions.

Key Responsibilities

  • Architect & Develop: Help drive the planning, building, and deploying APIs and microservices, focusing on high availability and superior performance at scale.
  • Strategic Collaboration: Partner with product management, engineering, and DevOps teams to define API guidelines, governance models, and integration patterns that drive alignment across the organization.
  • Security & Compliance: Implement and enforce authentication, authorization, and encryption standards (OAuth2, JWT, API key management) to protect assets and meet industry regulations.
  • Optimize & Innovate: Leverage caching, rate-limiting, and advanced monitoring tools (Prometheus, Grafana) to maximize throughput, minimize latency, and ensure proactive issue detection.
  • Technical Leadership: Conduct rigorous code reviews, mentor junior engineers, and champion best practices in API design and microservices architecture to maintain technical excellence.
  • Cloud & Containers: Utilize AWS, GCP, or Azure to host and orchestrate microservices, employing Docker and Kubernetes for efficient, containerized deployments.
  • Data Integration: Integrate APIs with Databricks, Spark, or Snowflake to facilitate advanced analytics and real-time data processing, enabling faster, data-driven decisions.
  • Documentation & Reliability: Produce developer-centric documentation and implement thorough testing to minimize downtime while ensuring consistent, high-quality API experiences.
  • Continuous Improvement: Stay current with emerging trends in API development—like serverless computing, edge computing, and new security frameworks—to continuously evolve our ecosystem.

Required Qualifications

  • Education: Bachelor’s degree (or foreign equivalent) in Computer Science, Applied Mathematics, Statistics, Machine Learning, or a closely related field.
  • Experience: 5+ years in API development, focusing on RESTful and GraphQL APIs.
  • Programming: Proficient in Python, Java, Node.js, or Go.
  • API Management: Hands-on experience with Mulesoft, Kong, Apigee, AWS API Gateway, or Azure API Management.
  • Architecture: Strong grasp of microservices architecture and event-driven design patterns.
  • Cloud & Containers: Expertise with AWS, GCP, or Azure and containerization (Docker, Kubernetes).
  • Security: Advanced knowledge of OAuth2, JWT, and API key management.
  • Optimization Tools: Familiarity with caching, load balancing, and monitoring (Prometheus, Grafana).
  • DevOps & CI/CD: Knowledge of CI/CD pipelines and DevOps practices for streamlined deployments.
  • Big Data Integration: Experience working with Databricks, Spark, or Snowflake.
  • Soft Skills: Excellent problem-solving, attention to detail, and ability to thrive in fast-paced environments.

Preferred Qualifications

  • Serverless Tech: Experience with AWS Lambda, Google Cloud Functions, or Azure Functions.
  • Messaging: Familiarity with Kafka, RabbitMQ, or other event-driven frameworks.
  • Database Skills: Understanding of both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB, DynamoDB) databases.
  • Agile Environment: Background in agile development settings.
  • Industry Experience: Healthcare experience is a plus.
  • Leadership & Communication: Strong communication skills and the ability to mentor and guide team members.
